CALCULATING-MACHINE Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed January 17. 1906. Serial No. 296,491.

T o all whom it may concern:

Be it known that I, HYMAN ELI GoLD- BERG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Calculating-Machines, of which the following is a specification.

My invention relates to calculating machines including calculating attachments to typewriters and the object of the invention is to provide reliable and simply constructed means for preventing the travel or shifting of the totalizer during the period when the totalizer wheels are being operated to register the digits.

In the typewriter-attachment form of machine which is' shown, the totaliZer travels past a master wheel so as to bring the totaliZer wheels into mesh therewith seriatim, and it is the rotation of the master wheel which causes rotation of the totalizer wheels. In order to make sure that the totalizer will not shift during the rotary movement of the master wheel it is desirable that the detaining means become operative upon the totalizer somewhat prior to the commencement of rotation of the master wheel and remain operative until somewhat after the completion of rotation of the master wheel; and to obtain a mechanism operating in this manner is one of the objects of my invention. In this particular among others, the present mechanism is an'improvement over the retaining mechanism shown and described in my prior atent application filed May 2S, 1904 Seria N o. 210,158, for in said prior application the detaining device is operated by the movement of the master or setting wheel itself and hence said detaining device is not operative either before or after the period of rotation of the setting or master wheel.

In this application I have indicated to a limited extent the construction of mechanism for inducing full key stroke and for restoring the keys and all connected parts to original position in case of an incomplete key stroke. I do not herein claim such mechanism however as the same forms the subject of a separate application for Letters Patent filed by me January eighth 1906, Serial No. 295,132.

I obtain the objects of my present invention by the mechanism illustrated in the accompanying drawing in which ,2

Figure 1 is a general front elevation of a typewriter attachment embodying my invention. Fig. 2 is a transverse sectional elevation thereof taken on line 2 2 Fig. 1. Fig. 3 is a plan view showing the relationship of the digit pieces, toothed driving sectors, intermittently rotating shaft and digit shaft. Fig. 4 is a face view of a digit iece showing its relation with the locking sha t and locking pinion. Fig. 5 is a sectional view taken on line 5*-5 Fig. 4. Fig. v6 is a sectional view similar to Fig. 5, but showing the intermittently rotating pinion rotated one eighth of a revolution from the position shown in Fig. 5. Figs. 4, 5 and 6 serve to illustrate the coperation of the digit pieces with the said pinions and shaft. Fig. 7 is a fragmentary detail view of the gearing for transmitting rotation from the digit shaft to the connecting or valuating shaft. Fig. 8 is a fragmentary plan view of the intermittently moving and digit shafts and of the forked piece which operates the detent or arresting member. Fig. 9 is a fragmentary view looking from the back of the totalizer showing the rack which travels in unison with the totalizer and forms part of the detaining device.

Similar letters refer to similar parts throughout the several views.

In many particulars the machine here shown is the same as the one shown and described in Patent No. 782,554 issued to me i February 14, 1905.

The parts which are especially concerned with the present invention are illustrated in Figs. 1, 2, 8 and 9 of the accompanying drawing.

The form of totalizer here indicated is fully described in Patent No. 710,772 issued to me October 7, 1902 although it is to be understood that various other totalizers might be employed in substantially the same manner to produce the same results.

Referring to the drawings, l represents the typewriter framework which supports the laterally shiftable typewriter carriage 2 and the typewriter keys 3. The typewriter keys are reciprocatory and the depression and rise of a key permits the carriage to escape laterally one step, the carriage being urged by springs or otherwise to travel laterally as the result of the operation of a key. As this is the ordinary typewriter construction and as the precise construction f is immaterial, the carriage escapement mechanism is not illustrated. Each of the number keys of the typewriter is connected to a driving sector 4 by means of links 5 or otherwise in such manner that the reciprocatory movement of the key will produce a reciprocatory movement of the driving sectors about shaft 6 as an axis. Said driving sectors are mounted so as to rotate independently upon said shaft and are provided with ear teeth adapted to mesh with the gear teeth 7 of the digit pieces 8. Said sectors are prevented from lateral movement on shaft by means of the spacing collars 6a or other suitable means. There is a digit piece for each of said driving sectors, and they are mounted upon shaft 9 in such manner. as to be both independently rotatable and independently shiftable thereon. Shafts 6 and 9 are rotatably supported in suitable portions 10, 11, 12 and 13 of the stationary' framework. The lateral shifting of the digit pieces upon their shaft is caused by pins 14a which are rigidly fixed in a stationary frame portion 14 and are adapted to act upon the inshifting cams 15 and outshifting cams 16 on the digit pieces as best illustrated in Figs. 2, 3 and 4. The parts are so constructed that when a driving sector is rotated about shaft 6 it causes the rotation of the corresponding digit piece about shaft 9 and also causes the lateral shifting of the digit piece lengthwise of shaft 9. The faces of gears 7 are wide enough to remain in mesh with the driving sectors 4 in both shifted positions of the digit pieces.` In the preferred design here shown, said digit pieces perform two functions one of which is to rotate the digit pinions 17 which are rigidly fastened to or integral with digit shaft 18, and the other function is to rotate the pinions 19 and 20 which are rigidly fastened to or integral with the intermittently rotating shaft 21. Said shaft 21 also performs two functions in the design here shown, one function being to cause the locking of the digit shaft and the other function is to cause the operation of the totalizer arrester or detaining device for preventing lateral shifting of the totalizer during the act of registration thereon. It is not essential, although it is desirable, that shaft 21 should thus perform two functions, but its ability to perform said first function is not herein claimed as novel, this having been shown in said prior patent No. 782,554. The construction whereby said shaft 21 operates the totalizer detent is claimed to be novel but first the construction of the valuating parts which are operated from the digit shaft will be described.

The digit pinions 17, and consequently shaft 18, are rotated by the toothed digit sectors 22 which are most clearly shown near the bottom of Fig. 2. Said digit sectors are incomplete toothed gear wheels, the number of teeth in each depending upon the value of the figure key to which it is connected. In

the present construction, the 1 digit sector has one tooth, the 2 digit sector two teeth, and so on. The relation of the parts is such that a digit sector will be in mesh with its digit pinion during the forward stroke of the digit sector' but will be shifted out of mesh after the completion of the forward rotation so that a digit sector will rotate back to original position without rotating the digit pinion. Consequently the digit sectors rotate backward and forward but the digit pinion shaft rotates always in the same direction, and the amount of rotation depends upon the value of the key temporarily in action. On shaft 18 is rigidly fixed a pinion 23 which meshes with gear 24 rotatably mounted on bar' 25. Rigidly fixed to gear 24 is a bevel gear 26 which meshes with bevel pinion 27 rigidly fixed on shaft 28. Rigidly fixed on shaft 28 is a bevel pinion 29 which meshes with a bevel gear 30 rigidly fixed. to the master or setting wheel 31. Any other suitable connections, however, may be substituted for transmitting motion from shaft 18 to master wheel 31. Said master wheel is rotatablymounted on bar 32 supported in suitable stationary brackets Said master wheel is adapted to mesh scrz'atim with the wheels 34 of the totalizer 35 for registering the digits on said totalizer.

Now as to the arresting or detaining device which is the special feature' of the present invention. It has been above stated. that lthe shaft 21 rotates intermittently. This is accomplished in the same manner as it is in my aforesaid patent No. 782,554 and in my companion application filed January eighth 1906 Serial No. 295,132. The said pinions 19 and 2O which are fast on said shaft 21 each have four teeth corresponding to the alternate teeth of an eight-toothed gear wheel, that is, they 'are like an eight toothed gear wheel from which the alternate teeth have been. cut away and they are so arranged upon said shaft that a tooth on one is opposite to the space between teeth on the other, so that when they are viewed from the side they have the appearance of forming a complete gear as illustrated in Figs. 5 and 6. Upon each digit piece 8 are three disk sectors 36, 37, and 38 best shown in Figs. 2, 4, 5 and 6. The disk sectors are so located on the digit pieces that when the digit pieces are in normal position, as shown in Figs. 2 and 4 and the'parts are viewed from the side as in Figs. 5 and 6, the ends of said sectors appear to overlap .each other, the overlapping areas corresponding to gear teeth suitable for engaging the teeth of the pinions 19 and 20.

The construction and arrangement is such that, for each rotation of a digit piece in the forward or positive direction, shaft 21 is twice rotated one eighth of a revolution, in

Ithe meantime being locked by the action of disk sector 37 on plmon 20 as shown 1n Fig. 6. Before and after each of these partial first by sector 36, as shown in 5, and last by sector 38. The actions of the disk sectors on their pinions occur only during the forward or positive rotation of the digit pieces, the disk sectors being shifted out of line during their return er negative 'rotation by reason of the action of the pins 14 on the outshifting cams 16. Said disk sectors are so timed with reference to the toothed digit sectors 22 on said digit pieces that said toothed digit sectors will cause the rotation of the digit shaft 18 to occur during the interval between the tuvo partial vrotary movements of the shaft 21. And it will he noted that consequently the shaft 21 is held fast, that is, locked during the rotation of the digit shaft; also that the shaft 21 commences its movement before the digit shaft does and finishes its movement after the digit shaft does. lt is as a result of this fact that the special value of this invention arises, for it is evident that a totalizer detaining device operated by or from shaft 21 Will commence to be operative before the registering action begins and will not cease to be operative until after the registering action is complete. Thus there is a slight period of time elapsing both before and after the movement of the master Wheel, when the totalizer is positively detained. It is apparent that various devices, operative from the intermittently moving member 21. might be constructed, and a suitable and convenient one is here illustrated, being best shown in Figs. 2 and S.

Upon bar 25 or other convenient support a reciprocating piece 39 is pivotally mounted. It has two forks or branches 40 and 41 adapted to straddle the cam 21L in suchA manner as to be positively reciprocated first in one direction and then in the other every time said cam is rotated one eighth of a revolution. Said cam is rigid on shaft 21 and by preference its form is identical With that of the pinions 19 and 20. A connecting rod consisting preferably of the parts 42, 43, and 44 serves to connect said reciprocating piece 39 with the detent 45. Parts 42 and 44 are threaded rods pivotally connected to piece 39 and 45 respectively and oined by means of the sleeve 44.

The connecting rod p arts h ave right and left 5 stationary guide bar 49 and carry the totalizer 35. Said slide is moved in unison with rotary movements said shaft is also locked, the typewriter carriage by means of the arm 49 depending therefrom and engaging said slide, or in any other suitable manner.

It has been mentioned that the shaft 21 performed two functions. The first function, that of operating the totalizer detaining device has been above described and the second function will now be referred to. This second function is to prevent/accidental rotation of the totaliZer-opcrating member. To this end a nose 39il is formed on piece 39 and adapted to enter between the teeth of a pinion 18 on shaft 18. Said pinion is rigid on said shaft and by preference is a counterpart or is actually one of the digit pinions 18.

` By thus making the single piece 39 to cause.4

both the arresting of the totalizer and locking of the digit shaft the mechanism is simplified and at the same time rendered more reliable and positive in action as the parts are more closely correlated.

Although for convenience in the description and some of the claims the totalizer is referred to as doing the traveling it will be understood that it is innnaterial whether it or the actuating member does the traveling, the essential characteristic being that one travels relatively to the other.

l do not herein claim anything With reference to an auxiliary master or setting Wheel or its controlling devices as this forms the subject of a separate patent application filed May 28, 1904, Serial No. 210,158.
